OIL CAN.

Application filed May as,

This invention relates to new and useful improvements in oil cans andhas for its main object a construction of can, wherein, mechanism isprovided for automatically forcing the oil from the can.

Another object of the invention is the provision of automatic mechanism,the action of which can be readily controlled.

Besides the above, my invention is distin uished in the combination ofmanually coll apsible means for exerting pressure on the oil in the canin combination of a manually operating valve controlling the flow of theoil from the can.

lVith the above and other objects in view the invention consists in thenovel features in construction, the combination and arrangement of partshereinafter more fully set forth, pointed out in the claims and 7 shownin the accompanying drawings in which Fig. 1 is a vertical sectionalview of my improved oil can.

Fig. 2 is a sectional view on the line 22 of Fig. 1.

Fig. 3 is a sectional view on the line 33 of Fig. 1.

Again referring to the drawing the numeral l designates a casing havinga top 2 and removable bottom 3. The top 2 is provided with a neck 4 atthe bottom of which is arranged a flange 5. A removable valve member 6is seated in the neck and rests upon the flange 5. This member 6 has abore 7 and a valve seat 8. Associated with the valve seat 8 is a valve 9attached to the 3138111 10 to the outer end of which is attached thebutton 11. A spring 12 acts against the button to hold the valve closed.The spout 13 of the oil can has a flange 14 engaging around the member 6and is engaged by the ring 15, threaded to the neck 4.. Thus it will beseen that the spout and valve member is effectively held together andmay be readily removed. For this purpose the valve stem 10 is composedof detachable sections as indicated at 16. Top is also provided with afilling cap 17 Slidable in the casing 1 is a plunger 18 acting againstthe body of oil in the casing. My improved manually controlledautomatically operating mechanism for exerting pressure upon the pistonand thereby subjecting the oil to a constant pressure consists of acontrol spring 19 of a collapsible formation having one end fixed to thepiston as indi- 1924. Serial No. 716,503.

cated at 20 with the other end attached to the bottom 3. A springpressing device 22 engages over a convolution of the spring and isoperated by the crank element 23 mounted in the bearing 24. It will bereadily apparent that by turningthe springpressed device 22, the spring19 will be gradually collapsed in order to move the plunger 18 towardthe bottom of the can for refilling the same and by turning the device22 in the opposite direction, the spring will be gradually released,forcing the plunger 18 toward the spout 13 for dispensing the contentsof the can. The rotation of this device causes the spring to becompressed under the device for moving the piston downwardly forrevolving the can.

From the foregoing description taken in connection with the accompanyingdrawings it will be apparent that by opening the valve at the top of thecan the spring action will force the piston forwardly for automaticallyforcing the oil from the can.

It is, of course, to be understood that various other types of operatingdevices may be used for collapsing and holding the spring during thefilling operation and the valve device at the top of the can may beconstructed in various other ways and associated with the casing invarious other manners, and therefore, I do not desire to be limited inany manner except as set forth in the appending claims.

Having thus described my invention what I claim is 1. An oil canincluding a casing, a spout projecting from the casing, a plungermovable in the casing, a coil spring confined in the casing and havingan end portion connected to the plunger and an opposite end portionconnected to the casing, and a manually rotatable member within thecasing and defining portions adapted to work over and along theconvolutions of the coil spring for contracting and expanding the coilspring to move the plunger in reciprocatory action within the casing.

2. An oil can including a casing, a spout projecting from the casing,manually operated means controlling communication between the spout andthe casing, a plunger movable in the casing, a coil spring confined inthe casing and having an end portion connected to the plunger and anopposite.
